Python: Iterate a given list cyclically on specific index position
Python List: Exercise - 181 with Solution
Write a Python program to iterate a given list cyclically at a specific index position.
Sample Solution:
Python Code:
def cyclically_iteration(lst,spec_index):
result = []
length = len(lst)
for i in range(length):
element_index = spec_index % length
result.append(lst[element_index])
spec_index += 1
return result
chars = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h']
print("Original list:")
print(chars)
spec_index = 3
print("\nIterate the said list cyclically on specific index position",spec_index,":")
print(cyclically_iteration(chars,spec_index))
spec_index = 5
print("\nIterate the said list cyclically on specific index position",spec_index,":")
print(cyclically_iteration(chars,spec_index))
Sample Output:
Original list: ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h'] Iterate the said list cyclically on specific index position 3 : ['d', 'e', 'f', 'g', 'h', 'a', 'b', 'c'] Iterate the said list cyclically on specific index position 5 : ['f', 'g', 'h', 'a', 'b', 'c', 'd', 'e']

Python: Tips of the Day
Given a predicate function, fn, and a prop string, this curried function will then take an object to inspect by calling the property and passing it to the predicate:
Example:
def tips_check_prop(fn, prop): return lambda obj: fn(obj[prop]) check_age = tips_check_prop(lambda x: x >= 25, 'age') user = {'name': 'Owen', 'age': 25} print(check_age(user))
